Description

The OPA2686 provides two very low noise, high gain bandwidth, voltage feedback op amps in a single package. Operating from a low 12mA/channel quiescent current, each channel provides a 1.4nV/ÖHz input voltage noise with a 1.6GHz gain bandwidth product.

Minimum stable gain is specified at +7V/V while exceptional flatness is guaranteed at a gain of +10.

The combination of low noise, high slew rate (600V/s), and broad bandwidth allow exceptional xDSL differential receivers to be implemented. Decompensated, low noise voltage-feedback op amps are ideal for broadband transimpedance requirements.

Thedual channel OPA2686 provides matched channels for high speed differencing transimpedance requirements.

With over 200MHz bandwidth at a gain of 20dB, excellent gain and phase matching is provided at IF frequencies for matched I and Q channel preamps.
